100% crop

I'm still not getting what is meant by 100% crop

Recently, an agency asked me to check my images at 100% crop

Is it cropping an small part of an image at the native resolution of a camera(s) then selecting a small portion of an image or something else?

If they ask you to check the images at 100%, they want you to zoom in to 100% and go over the image for any halos, dust, artifacts, etc. A "100% crop" just indicates that you've cropped the image as far as it can go before pixelating, i.e., you're view the image pixel for pixel.

This is all above my head

Let me expand.

If you merely want to check an image at 100%, all you need to do is set your image viewer to 100% (or 1:1) magnification. You will indeed be seeing only a section of the image, magnified, but you aren't truly cropping it.

On the other hand, if you are to submit a 100% crop (perhaps appending it to a post on this board), you need to crop out of your picture a section small enough (say 600x800 pixels) to be displayed on most monitors pixel-to-pixel without any resizing taking place. That crop you save as a new file.

The latter are the samples you see on this board when someone is showing the image of only one eye for people to judge the sharpness achieved.

1:1 Lr

I don't need to submit 100% crop, just submit the original photo but they said to check it at 100% to check it for "defects" such as softness and noise etc

So the first option applies. They want you to check your images in detail, at 1:1 magnification, before you send them over.
They needn't have used the word "crop" and confused the issue.

Ah right, so they did confused me, hahaha, thanks

I've seen this before and have wondered similar...

I completely follow the above, whether in Lr, PS, or even Windows Viewer, when viewing an image at 100%. However, how do you make a "100% crop"?

The only way I would know to do this would be to view at 100%, then do a screen capture. Is there a way that people do this within Lr or Ps natively?

Just keep cropping down until the full size and 1:1 are the same thing, i.e., when you select 1:1 it no long does anything.

You don't need a screen capture, all you need is make a crop so tight that only a small number of pixels is kept in use, and that crop is saved as a separate image.

Being small, it will be displayed at 100% (no resizing required to fit into the screen). By that virtue it assumes the name "100% crop".

Here is the cropping being carried out on the picture in full view (1). The resultant crop is saved as a separate file and posted as a "100% crop" (2).

The 135L is a splendid lens, BTW ...

I was just about to type that not only is that a great example of a100% crop, but a great example of a sharp photo!
